Myocardial
T2* mapping is proven value for the assessment of myocardial iron content and
tissue oxygenation. This study examines the feasibility of highly accelerated
fast-spin echo based T2* mapping. Acceleration is accomplished by (i) inner
volume imaging, (ii) regional saturation slab based blood suppression,(iii)
partial Fourier and (iv) k-t BLAST. A four-fold acceleration is feasible
without compromising image quality and the accuracy of calculated T2* values.
